Abstract
The utility model discloses a bent axle torsional oscillation reducer which consists of an internal ring, an external ring and a damping ring, with the damping ring positioned between the external surface of the internal ring and the internal surface of the external ring, the internal ring consisting of a wheel boss which is provided with a wheel boss hole, and an inner ring and a wheel rib connecting the inner ring and the wheel boss. The external surface center of the inner ring is provided with a heave in the axial direction. Thanks to such a structure, the internal ring and the external ring are connected into a whole through the damping ring, which satisfies the requirement of the power transmission and movement. The adjustment in the natural frequency of the bent axle leather wheel absorbs the vibration and lowers the noises so that the noise produced by the motor is reduced and the vibration of the motor is decreased.
Description
Technical field
The utility model relates to field of automobile, especially relates to a kind of crankshaft vibration damper.
Background technique
Domestic torshional vibration damper all is to make with single metal material at present, in transmitting torque and movement process, be rigidly connected with bent axle, the vibration of bent axle axle system is not passed on the engine accessory wheel system by belt pulley fully damply, and the overall noise of motor and vibration are bigger.
The model utility content
Technical problem to be solved in the utility model is: a kind of vibration that absorbs bent axle axle system is provided, thereby reduces the overall noise of motor and a kind of crankshaft tortional vibration damper that reduces to vibrate.
For solving described technical problem, the technical solution of the utility model is: a kind of crankshaft vibration damper, it is made up of inner ring, outer ring and damping ring, described damping ring is between inner ring outer surface and inner surface, and described inner ring is made up of the spoke of the wheel hub with wheel bore, inner ring ring, connection inner ring ring and wheel hub.
The middle part of the axial direction of described inner ring outer surface has a projection.
The spoke of described inner ring can be uniform spoke, and the big end of each spoke links to each other with wheel hub, and small end links to each other with the inner ring ring, and the spoke cross section is oval.
The spoke of described inner ring can also be the disc of ring, has uniform through hole on the disc of ring.
Described wheel bore is coniform along the hub axis direction.
The cross section of described wheel bore reaches the rectangle that cooperates with keyway by the circle that cooperates with bent axle and forms.
Described outer ring can be stepped shaft.
The V-shaped groove that can have equidistant intervals on the outer ring surface of described outer ring.
Can have the wedge trough of belt on the outer ring surface of described outer ring.
The utility model adopts such structure, and inner ring and outer ring are combined into one by damping ring, can satisfy the requirement of transferring power and motion, the natural frequency of tuning crank pulley, can absorb vibration and reduce noise, reduce the noise of motor, reduce the vibration of motor.
